Ok, I can't hold it in... Nanotherm PCM+ thermal paste is awesome stuff does
a bit of discoloration
on the bottom really make a difference if performance is good?!?
(The Computer Engineer) says: "Most manufactures of Copper heatsinks
use a thin coating of laquer or other sealant to ensure that the copper doesn't
react with the Oxygen and form the all to often seen 'green facia' or weathering.
This would be fatal to thermal conductivity, so the coating is there to protect
the copper from becoming copper oxide. However, it is possible that these 'laquers'
are interacting chemically with the compounds used in the PCM from Nanotherm.
